Astraea

Astraea (アストレア, Asutorea) is a "Close Combat Angeloid, Type Delta". She becomes the last First Generation Angeloid to break free from the Man of Synapse.

Appearance
She weighs 48 kilograms and is 159 cm tall. Her bust is 91 cm, her waist is 56 cm, and her hip is 86cm. Her wing's are white and her wing type is stated to be "Super Acceleration".

Personality
She is somewhat of an airhead and has limited intelligence due to having low processing power, paying homage to the dumb blonde stereotype.

Astraea also harbors feelings for Sakurai Tomoki despite often being a target to his perversions. However, despite her lack of intelligence, she does display a good level of common sense in situations where Ikaros would be clueless about. Ironically, she is also regularly found starving due to the fact that she does not know how to hunt or obtain food by her own means, which was shown when she once buried herself to the ground because she tried to obtain nutrients the way plants did.

History
When she is ordered by Man of Synapse to eliminate Ikaros, she breaks off her chain and engages in combat with Chaos.

Astraea Arc
Astraea is originally sent down to Earth by the mysterious Man of Synapse shortly after the the failure of the Harpies to recover Ikaros and Nymph and eliminate the one who has taken them under his wing, which is Tomoki Sakurai. She makes her arrival on Earth in the woods outside of Sorami City right in front of Eishiro Sugata, who assumes that this new arrival from Synapse is nothing but trouble for Tomoki and sets off to locate him and warn him about this new threat.

Abilities
Hyper Acceleration - According to Daedalus, Astraea has been granted with 'Hyper-Acceleration' wings, which allow her to accelerate faster than any of the Angeloids. It can be assumed that these wings grant extreme aerial maneuverability, giving Astrea the edge in close combat by allowing her to quickly evade strikes and change her direction. However, Astrea still loses out to Ikaros in terms of her top-speed.

Battle Power - As stated by Nymph, and later by Daedalus, Astraea's battle power is greater than even Ikaros's up close. Daedalus even went as far as saying "an Angeloid that can match Delta in close-range combat does not exist". However she is vulnerable against any Angeloid with long-range weapons as she has no long-range weapons.

Pandora - Also know as the "Self-Evolution Program", it allow oneself to grow in power through time and the absorption of other thing. Can also repair broken systems and functions. The program that Astraea has is also the one used by Ikaros and Nymph, and is supposedly the ultimate program. Even the Man of Synapse feared its power.

Tomoki is Astraea's unofficial master.

Man of Synapse
The Man of Synapse was the former master of Astraea.

Trivia
